Abstract:With the help of cast-in-place surface alloying,the composite layer with WC particles and high chromium cast iron on the surface of grey iron was achieved under a right technology,and then. its microstructure and wear resistance was studied. The results show that the layer is smooth in shape,even in composition,combined closely with base and has high abrasion resistance,and that the service life of the mixer vane by cast-in-place surface alloying on grey iron increases over two times,compared with that of the vane made of Q235 steel.
Keywords:cast-in-place surface alloying WC particle high chromium cast iron wear resistance
